' 1 Claim.

This invention relates to a ventilating window sash, and it is an object .of the invention to provide a sash of this kind wherein the upper pore tion of the sash is constructed .in a manner to provide for a screened opening, together with a hood or canopy carried by the sash extending outwardly from the outer face of the sash and disposed over the screened opening in a manner to effectively prevent. rain, snow and other elements passing through the screened opening.

Another object of. the invention is to provide a sash of this kind constructed to provide a screened openingin its upper portion, together with a hinged door carried by the sashfor regulating the screened opening and wherein means are provided to readily and'efiectively maintain said door in selected adjusted positions.

The invention consists in the details of construction and in the. combination and arrangement of the several parts of my improved ventilating window sash whereby certain important advantages are attained, as will be hereinafter more fully set forth.

In order that m invention may be better un-. derstood, I will now proceed to describe the same with reference to the accompanying drawing, wherein:

Figure 1 is a fragmentary view in elevation of a window sash illustrating my invention.

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1.

Figure 3 is a longitudinal sectional view taken throughthe upper end portion of the operating member as illustrated in Figures 1 and 2, and

Figure 4 is a view of the mounting fixture for the operating member.

As disclosed in the accompanying drawing, W denotes a conventional window frame in which is snugly fitted in the usual manner a' window sash S. This window sash S may be of a storm type, if desired, and is only illustrated in fragment as the lower portion of the sash forms no particular part of the invention.

The side rails I of the sash have interposed therebetween at the upper portion thereof a cross member 2 spaced a desired distance below the top rail 3 of the sash S to provide a ventilating opening 4. This opening 4 extends substantially entirely across the upper portion of the sash and marginal walls of the opening and are provided with rabbets 5 to allow a snug fit over the opening 4 of a screening element 6. This element 6 serves to prevent insects or the like entering through the opening 4.

The top rail 3 has suitably fixed to its inner faceat desiredipoints spaced lengthwise, thereof the blocks 1,. These blocks 1' are elongated and have their major axes disposed: lengthwise of j the rail 3., The underlongitudinal edged of. each of these blocks 1 is spaced-a slight istan'ce upwardly from the adjacent lower longitudinal edge ofthe rail 3. J I;

- Anchored, as at 8, to the outer faces of these blocks 1 are leaves 9 of the ventilating hinged members. The second leaves I0 of these :hinged members are securely fastened at ll .to theiouter faces of an imperforate 'door. or shutter 42. This door or shutter "is of a length to slightly overlie the inner marginal portions of the siderails] of the sash S and of awidth .to extend above and below;=the ventilating opening ,2 ,whenthe door or shutter" is in. fullygclosed position.'

As is particularly illustrated inFigure 2, it is tobe noted that thej'pintle M, of. each of the hingedmembersisso positioned as .to allow the upper marginal portion oft'he door or shutter 42 to buttfrom below:. the- ,lower;,marginal edge of each of the blocks-fl,,th1.1$;,&Wi1'lgiOl closeiconw tactof the marginal: portions-ofithedoor or shut-. ter :42 with the inner: facesofjtherails I, and} andmemberi. I -t:.i:;p .1r i 1 An end portion of the door or shutter 42 has non-rotatably secured thereto, as at 15, an outstanding crank member 4l. This member 4|, partially overlies the adjacent side rail l of the sash S.

The outer face of the top rail 3 of the sash S is provided therealong with a slot 2|, said slot extending slightly inwardly of the adjacent portions of the side rails I. Snugly fitting within this slot 2| is a rearwardly disposed lip 22 carried by and extending along the upper margin of a flange 23 at the top of a protecting hood H. This flange 23 has close contact with the outer face of the top rail 3 immediately adjacent to the opening 4 and said flange 3 is tightly held against said rail 3 by the suitable members, not shown.

The flange 23'hereinbefore referred to is along the upper margin of a downwardly and outwardly disposed front plate 25 of the hood H, said plate being herein disclosed as approximately 45 degrees to the vertical. The ends of this front plate 25 are defined by the inwardly disposed end plates 26 having their inner margins in close contact with the side rails of the sash S.

The lower margins of the end plates 26 are disposed on downward and inward inclines at approximatel right angles to the plate 25 so that the lower portions of the end plates 26 will extend a material distance below the opening 4,

As is illustrated in Figure 2, it is also to be noted that the front plate 25 of the hood H is of a size to have its marginal portion a pronounced distance below the opening 4. The lower marginal portion of the front plate 25 and each of the end plates 26 is defined by an inwardly disposed strengthening rib 29. It is also to be stated that the walls 25 and 26 of the hood H and the associated parts are preferably formed from a single blank of sheet metal. 1

With the hood H applied to the outer side of the sash S at the top thereof, rain, snow or the like are effectively prevented from passing in through the opening 4 yet in no way afiecting the desired ventilation. It is also to be noted that the hood H is carried by the sash S and that the screening element is also carried by the sash S and free of the hood H. This is of advantage s that when desired the hood H can be removed without in any way affecting the efficiency of the ventilating opening 4 and the door or shutter 42coactingtherewith. I 1

While 'I have shown 'the'sash S as of a stationary type, it is believed totbe obvious that it "can be made ofa size tobe' slidably mounted withinits frame.

A sight opening 30 of the sash below the member -2 'is'closed by a panel 3| of glass although; of 'course, this -maybe varied without departing from the invention as herein embodied.

1 Mounted upon one ofthe vertical parting strips 33' of the window frame or casing is an operating member. 32. This member 32 comprises an elongated flexible flat strip having its lower end porwith the longitudinally spaced openings 38 which are adapted'to selectively receive an outstanding pin 39 carried by the lower portion of the plate 35 to look the member 32 in its various endwise adjustments.

The upper end portion of the member 32 has fixed thereto the inwardly disposed sleeve or tubular bearing 40 substantially at right angles to the member 32. Freely received within this sleeve or bearing 4|] is the outer or free end portion of thecrank member 4l,. which--.is carried by the door or shutter 42 and extendsjoutwardly beyond an end thereof, as clearl illustrated in Figure 1.

1 It is believed to be obvious that by moving the member 32 endwise in either an upward or downward direction, the door or shutter 42 may be adjusted as desired. This operation of the member 32 is readily permitted and facilitated by the pivotal mounting of the plate or fixture 35. s

From the foregoing description it is thought to be obvious that a. ventilating window sash constructed in'accordance with my invention is particularly well adapted for use .by reason ofiithe convenience and'facility..with' which it maybe assembled and operated.
